Executive summary:

In the acute immobilisation test with Daphnia magna (STRAUS) the effect of the saturated solution as limit concentration of the test item

1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoro-

(Batch number P00/001), was determined according to OECD Guideline 202 I. The limit test was conducted from 2002-04-03 to 2002-04-05 at DR.U.NOACK-LABORATORIUM FÜR ANGEWANDTE BIOLOGIE D-31157 Sarstedt.

A coating period of 14 days was carried out. The preparation method was chosen with regard to the test item properties and in accordance with the relevant guidance documents (OECD 2000, BAUA 2001). The study was conducted under static conditions over a duration of 48 hours. 20 test organisms were exposed to the saturation concentration and control. The saturation concentration was analytically verified by GC-analysis (for details see part 8). The mean measured concentration of the saturation concentration was 0.16 mg/L.

In the tested saturation concentration of 0.16 mg/L (mean measured concentration) no biologically significant effect was determined.

A reference test is carried out once per month with potassium dichromate as reference item and the reference toxicity determined. The EC50-value of the reference item at 2.1 mg/L after 24 h was within the prescribed concentration range of 1.0 to 2.5 mg/L according to AQS, DIN Guideline 38412 L 30.

Water quality parameters of pH-value and dissolved oxygen concentration measured at 0 and 48 h were determined to be within the acceptable limits. The validity criteria of the test guideline were fulfilled.
